Air flow diagram for B109BL300-22-SWC

I have a sanborn air compressor mode# B109BL300-22-SWC .


The header broke and is obsolete to purchase. I have bought a retro header but not sure of where do i install the check valve which did not come with the retro.

I need a flow diagram to see where to install it.

Also there is a dump valve on the check valve and not sure where it is installed, the old set up had a dump valve from the switch back to the compressor not the check valve. What do I do with the dump from the check valve ?

You can look up the style of your machine, and then there's probably a wiki or an article or two-hundred with a diagram. They're all very similar except for some "features" of the cheapo's at the big boxes.

If, after that, you have a more specific question, come on back...

Have fun...
